Abstract: PURPOSE:To prevent defective mold such as unpenetration, by providing a detecting device for detection of contact between the tip part of a casting pin for forming a hole and the surface of a cavity, in a mold for molding a container having a partition wall provided with a hole. CONSTITUTION:In a mold for molding a container 8 such as an oil tank having a partition wall 5 provided with a hole 4, a movable contact point 25 is arranged on the tip part of a casting pin 14 for forming said hole 4, a receiving contact point 24 is arranged on a wall surface 10a of a cavity abutting against said contact point 25, and both the contact points 24, 25 are connected by lead wires 27, 28 with a detecting circuit. When the casting pin is worn and damaged, both the contact points do not come into contact with each other, this noncontact is detected by a detecting circuit and injection is suspended automatically. Generation, therefore, of a deffective article whose hole on the partition wall is closed and unpenetrative does not occur.

Title: Signature decision system
Inventor: KOJIMA HARUHIKO
IPC: G06F3/0488
Filed: 1990-02-22
Abstract: PURPOSE:To accurately identify a signature writer at any place by matching two pieces of information on a holograph and pen pressure in combination and using pressure sensitive paper or a pressure measurement film for pen pressure measurement. CONSTITUTION:The pressure sensitive paper or pressure measurement film is superposed upon normal paper and then a signature writing means 1 easily obtains not only holograph information, but also pen pressure distribution information in signature writing. Those data are sent to a decision processing means 3 through, for example, a facsimile equipment 10 and the decision processing means 3 retrieves data in a signature data base means 2 to match two pieces of information on the holograph and pen pressure in combination. Consequently, any special device is not required at a place where the signature is written and the pen pressure information can be gathered although there is no limitation regarding the writing place, so accurate writer identification becomes possible as compared with a method which uses information only the holograph.

Title: Method for working titanium alloy
Inventor: KUBOKI ISAO
IPC: C22F1/18
Filed: 1993-03-01
Abstract: PURPOSE:To improve the plastic workability of a titanium alloy and also to improve strength and ductility by performing primary plastic working at a temp. not higher than the static recrystallization temp. at specific draft and then performing secondary plastic working at a temp. lower by specific temp. than the beta-transformation temp. CONSTITUTION:Plastic working, such as rolling, is done at a temp. not higher than the static recrystallization temp., particularly not higher than room temp., at 20-40% draft. Subsequently, without performing heat treatment, plastic working such as die forging is done at a temp. in the range between the beta-transformation temp. and a temp. lower by 250 deg.C than the beta-transformation temp. Because dislocation density to be a recrystallization driving force is increased by cold working in a titanium alloy containing large amounts of residual beta-phase, recovery and recrystallization occur during heating up to working temp. at subsequent plastic working or during heating and holding up to and at the above temp. or during forming at secondary plastic working, and the crystalline grains in the course of deformation are refined. Resultingly, deformation resistance is decreased and deformation velocity is increased. As a result, plastic workability is improved and structure is extremely refined, by which the ductility as well as strength of a final formed part can be improved.
